Help: Achieving stable 2000mhz DRAM value! =D

post #1 of 7
Thread Starter 
Hi all, with the help of this awesome community I was able to succesfully research and build my new PC. Alas the final stage is at hand, I require help in obtaining a stable overclock regarding the DRAM, FSB and CPU clock value.

System Setup:

Motherboard: Asus Crosshair 4 Formula
CPU: Phenom 1090T
RAM: DDR3 Corsair Dominator GT 2000mhz rated
PSU: Corsair HX1000W
CPU Cooling: Corsair H50
GPU: 2x 4890 Sapphire Radeon in Xfire
Case: Antec 1200



I do have past OC experience when I used to clock my Q6600 although I would like other opinions on this matter, if voltages are required to be tweaked then that is the one thing I defenitely need help on.

As a bit of a warm up exercise I simply enabled D.O.C.P (dram oc profiler) and selected 2000mhz, the PC would post however upon start up of windows it would simple restart. I did the same thing for 1800mhz and it worked no problem.

Kind Regards,

Max

Overclocking

I have a 1055T witht he same Board and i found overclocking to be a breeze, with any luck you should easily get 4.0Ghz....as you mentioned, if u know how to overclock, i wont give u a tutorial on that, just the voltages that seems ok on the hexacore phenoms: CPU-1.475V ( i think its the Turbo mode voltage) Memory Max 1.65-1.7 V, Northbridge 1.3V HT link 1.3V?.. im not at my comp now so thats all i can remember but like theres a couple for voltages that help just bring em up like .05 or something and its safe...I a Daredevil with my voltages so there up a bit higher than this xD

Memory

thats some nice memory you got so u can expect lots of performance...if u wanted it to boot up at 2000Mhz add a lil bit of voltage, should do the trick. But personally i prefer the lower clockspeeds and tighter ram cuz the phenoms seem to like it better that way and perform a bit better ( overclocking is a bit easier too i believe)

You need to have your DRAM voltages at 1.65V.

Havok: During preliminary tests I have managed to get past 4Ghz (by changing the multiplier or fsb clock) without any problems. When you get home could you please double check those voltages you posted?

Regarding the failed windows load, which voltage would that be attributed to?

As for the memory, when you say 'tighter' ram do you imply lower clock cycles? ATM my ram sits at 1333 mhz with clock cycles 9 9 9 24, surely the XMP timings of 8 8 8 24 would be more beneficial. Unless you mean to lower the clock to say 1184mhz with cycles 8 8 8 22. I could effectively run some benchmarks to test between the two once solve this thread.

Dorksterr: When I get home I'll tweak the voltage on the ram by 0.05 increments, and see if windows will load.

Would it be more beneficial to manually set the DRAM values or enable D.O.C.P and simply check to see if the timings and voltages match up with the SPD table shown on CPU-z and then make any changes.

Side Note (and bit off topic): I performed the Crosshair 4 North Bridge mod by filing down the screw stand things, this reduced the idle temp from mid 50's to mid 40's. If I encounter any erratic behaviour I will apply a better thermal paste. Mid 40's sound good?

they might not be rated for 2000 on amd, only intel.

take a look at this
https://shop.corsair.com/store/item_...spx?id=1235506

I know its not the same ram but it can give ya an idea
•2250MHz @ 8-8-8-24 using 1.65v on Intel P55 and X58 platforms
•1800MHz @ 6-6-6-18 using 1.65v on AMD 790FX (Socket AM3) platforms

I would try for 1600mhz @ 6-6-6-18 timings. 2000mhz is not very benificial on amd unless your northbridge is at 4ghz.

For temp on the NB in the mid 40's, thats not too bad. When stress testing for over several hours my NB can get that hot as well. In regards to hitting 2000MHz on the RAM, odds are you will have to do some tweaking on the CPU-NB VID setting in the BIOS. Even though the RAM kit is rated at 2000MHz, the memory controller built into AMD CPUs needs a little help to reach those speeds. I would say bump your CPU-NB VID up to somwhere between 1.3v and 1.35v and see if that helps stabilize the RAM.
